The main app that I use has a registration key which is in a .deb if I remember correctly. Anyway, I get no problems with this programme at all launching from the osso-statusbar app. I suppose different s/w vendors use different key systems but I'm surprised it conflicts. Can you use a command line launch for non-keyed apps withut problem?

I really like the quick launch - it makes a big difference for speed and simplicity of startup.
